Mason Adams, Frank Converse, Mariette Hartley, Robert Sean Leonard and Anne Pitoniak will form the new cast of A. R. Gurney's Ancestral Voices at Lincoln Center Theater on Oct. 24. They will replace Edward Herrmann, Blythe Danner, Philip Bosco, David Aaron Baker and Elizabeth Wilson.

Voices, now extended through Dec. 20, plays at the Mitzi Newhouse Theatre on Sunday and Monday evenings -- the LCT hit musical Contact's dark nights. In Voices, five actors sit on stage and read the script (making it easy for changing casts) about a family whose lives are turned inside out when young Eddie's grandmother unexpectedly divorces his grandfather to marry the grandfather's best friend.

Adams most recently appeared in Lake Hollywood Off-Broadway at the Signature Theatre Company. Leonard was part of the ensemble cast in last spring's acclaimed Broadway revival of The Iceman Cometh, starring Kevin Spacey. Hartley was seen earlier this fall at Boston's Huntington Theatre in Mrs. Warren's Profession.

Tickets for any of Lincoln Center Theatre's shows are available through Tele Charge at (212) 239-6200.
